Viewing this question abstractly, you are asking how do I get better at <hard thing>? The answer is the same. Progressive load. Do something that you struggle with but can complete until it is no longer a huge struggle, then do something harder, progressively. Both biting off more than you can chew and not biting enough will prevent progress. The key thing to understand is that the feeling of struggle is exactly the feeling of learning, particularly for older people. The feeling of struggle is not metaphorically, but physically the precursor to learning. The feeling of struggle is marking brain cells to be altered during sleep (layman's translation of huberman podcast) which is when your brain actuates learning. So you must seek the feeling of struggle to be learning.
